Oct 14, 2020 · Create training examples and targets. Next divide the text into example sequences. Each input sequence will contain seq_length characters from the text. For each input sequence, the corresponding targets contain the same length of text, except shifted one character to the right. So break the text into chunks of seq_length+1. ing data. Figure 1 shows a good example of this. The structured SVM (Tsochantaridis et al., 2004; Cherry and Foster, 2012) was used to learn the weights for a Chinese-English Hiero system (Chi-ang, 2005) with just eight features, using stochastic gradient descent (SGD) for online learning (Bottou, 1998; Bottou, 2010). The weights were initialized Consider running the example a few times and compare the average outcome. The first is a test to see how the model does at starting from the beginning of the rhyme. The second is a test to see how well it does at beginning in the middle of a line. The final example is a test to see how well it does with a sequence of characters never seen before.
